How to Share Wi-Fi from Phone to Phone: All Methods + Speed ​​Comparison

Are you in a situation where you urgently need to share the internet from a second phone, but don't have a router handy? Or do you want to save on mobile data by using an unlimited internet plan on one device? Sharing Wi-Fi from phone to phone is possible with at least in five ways — from the classic access point to hidden functions of Android and iOS.

In this article you will find Step-by-step instructions for all current versions of Android (12-15) and iOS (15-17), comparing data transfer speeds, battery consumption, and even less obvious life hacks—for example, how to share the internet without a password or through USB cableWe'll also address common errors (like "Unable to enable hotspot") and explain why some methods only work on certain smartphone models.

Spoiler: the fastest way is Wi-Fi Direct hotspot on Android 13+, but it requires both devices to support the technology. If you need to share internet from an iPhone to an Android device (or vice versa), you'll have to use workarounds—we've also described those.

1. Classic access point (Wi-Fi Hotspot) - a universal method

This is the most common method that works on all smartphones - from budget Xiaomi Redmi to the flagship Samsung Galaxy S23 Ultra And iPhone 15 ProThe idea is simple: one device becomes a "router," and the second connects to its network as a regular client.

Advantages of the method:

• 🔄 Works on all versions of Android and iOS
• 📶 Speed ​​up to 10–15 Mbps (depending on the tariff)
• 🔋 Moderate battery consumption (about 1–2% per hour)
• 🛡️ Encryption support (WPA2/WPA3)

Flaws:

• 📵 Some operators block data sharing (especially on unlimited plans)
• 🔌 The battery drains quickly if you don't connect it to a charger.
• 📱 You can't change the network name (SSID) on an iPhone without jailbreaking.

How to turn on hotspot on Android:

1. Open Settings → Connections → Mobile hotspot & tethering.
2. Tap on Mobile hotspot.
3. Turn on the slider and set the network name (Network name) and password (Password).
4. On the second phone, connect to the created network as if it were a regular Wi-Fi network.

How to turn on hotspot on iPhone:

1. Go to Settings → Tethering.
2. Activate the slider Allow others.
3. Remember the password from the section Wi-Fi password (it can't be changed without jailbreak).
4. On the second device, find a network with a name like this iPhone [your name] and connect.

⚠️ Attention: On some tariffs, operators (for example, MTS, Beeline, Tele2) limit the upload speed to 64–128 kbps, even if the donor phone has fast internet. Check your plan's terms in your personal account.

2. Wi-Fi Direct – sharing without a password (Android only)

Wi-Fi Direct — is a technology that allows devices to connect directly to each other, without a router. In the context of internet sharing, it works like a "passwordless access point," but with one caveat: Internet will only be available on the client phone, and the donor phone will remain without communication.

This method is suitable if:

• 🔒 You don't want to enter a password
• 📱 Both phones are Android (Wi-Fi Direct works differently on iPhone and is not suitable for sharing)
• 📶 You need maximum speed (up to 20–30 Mbps)

Instructions for Android 12–15:

1. On the donor phone, open Settings → Connections → Wi-Fi.
2. Tap on Wi-Fi Direct (on some firmware versions - Direct Share or Fast transfer).
3. Turn on visibility for other devices.
4. On the second phone, follow the same steps and select the donor phone from the list.
5. Confirm the connection on both devices.

Once connected, a notification will appear on the client phone about connecting to the Internet via Wi-Fi Direct. Important: Mobile internet will be disabled on the donor phone – this is normal.

Make sure both phones support Wi-Fi Direct (check in Wi-Fi settings)

Disable the access point on the donor phone (they conflict)

Make sure mobile data is enabled on the client phone (if you need to share its Internet)-->

⚠️ Attention: On phones Samsung With One UI 5.0+ Wi-Fi Direct may automatically turn off after 5-10 minutes of inactivity. To prevent this, add the connection to "Always Allowed" in the battery settings.

3. Bluetooth sharing – saves battery, but has low speed

If you need to share the Internet for a long time (for example, for the whole day), but at the same time saving battery life, Bluetooth is a good compromise. The speed will be low (up to 1–3 Mbps), but battery consumption is minimal (about 0.5% per hour).

Advantages of the method:

• 🔋 Minimal battery consumption
• 🔒 Connection without a password (only confirmation on both phones)
• 📱 Works between Android and iPhone

Cons:

• 🐢 Low speed (not suitable for HD video)
• 📵 Not all operators allow Bluetooth sharing
• 🔌 May be interrupted if the distance between phones is large (>10 m)

How to share internet via Bluetooth Android:

1. Turn on Bluetooth on both phones.
2. On the donor phone, open Settings → Connections → Bluetooth and tap on the name of the second phone.
3. Confirm pairing on both devices.
4. Return to Settings → Connections → Mobile hotspot & tethering.
5. Turn on Bluetooth modem.

For iPhone:

1. Pair the devices via Bluetooth (in Bluetooth settings).
2. On iPhone, turn on Settings → Personal Hotspot → Allow Others.
3. On Android, select iPhone from the list of Bluetooth devices and turn it on Use to access the Internet.

4. USB modem – maximum speed and stability

If you have USB cable (better the original), this method will give the most high speed (to 50–100 Mbps) And minimal delaysSuitable for:

• 🎮 Online games (for example, PUBG Mobile or Call of Duty)
• 📹 Streaming 4K video
• 📥 Fast download of large files

Restrictions:

• 🔌 You need a cable (preferably with support) USB 3.0)
• 📱 Doesn't work between iPhone and Android (only Android→Android or iPhone→Mac/PC)
• 🔋 The donor phone quickly drains its battery if you don't connect it to a charger.

Instructions for Android→Android:

1. Connect the phones with a cable (on the client phone, select the mode File transfer or USB modem).
2. On the donor phone, open Settings → Connections → Mobile hotspot & tethering.
3. Turn on USB modem.
4. On the second phone, the Internet will work automatically (a reboot may be required).

For iPhone→iPhone/Mac:

1. Connect your iPhone to another device via cable.
2. On iPhone, turn on Settings → Tethering.
3. On the second device, confirm trust for the connected iPhone.

5. Hidden functions: distribution via NFC and QR code

Few people know, but some phones can share Wi-Fi. without entering a password, using NFC or QR codeThese methods don't work on all models, but if your phone supports them, it makes connection much easier.

Distribution via NFC (works on Samsung Galaxy, Google Pixel, Xiaomi with NFC):

1. Turn on NFC and hotspot on the donor phone.
2. Place the second phone on the NFC chip (usually on the back).
3. Confirm the connection on both devices.

FAQ: Frequently asked questions about sharing Wi-Fi from your phone

Is it possible to share Wi-Fi from iPhone to Android?

Yes, but only through access point (Wi-Fi) or BluetoothUSB tethering and Wi-Fi Direct are not supported on iPhones when connecting to Android. Also, please note that you cannot change the network name (SSID) or password on iPhones without jailbreaking.

Why is the internet slow when sharing via USB?

Possible reasons:

• A cable is used USB 2.0 instead of USB 3.0.
• The donor phone is in the enabled mode File Transfer (MTP) instead of USB modem.
• The operator limits the distribution speed (check your tariff).

Solution: Try a different cable, switch USB mode, and check your APN (Access Point Name) settings on your mobile network.

How to share Wi-Fi from a phone without a password?

There are three ways:

1. Use Wi-Fi Direct (Android only).
